BTW, I carry a .22 caliber tool everywhere I go. I practice hitting six inch objects at distances from seven yards to twenty-five yards with as fast a presentation on target as I can manage. The secret is front site focus ... even my home defense tools are set up with the light located forward on the tool such that the front site is illuminated at the edge of the beam too.
Firefights and gun battles, especially in the civilian world, happen very quickly. There have been many many stories of people who have not hit a thing while they were blasting away, but scared the attacker off. Granted this is not the best approach, but getting into the fight is the first step.
Realizing the threat, getting TO your gun and then getting OUT your gun are all required before the first shot is even fired. That is while rule #2, fast beats slow, is listed prior to #3 a hit beats a miss.
Also, understand that #2 is NOT about the time between shots, nor the speed of the bullet. It is about getting into the fight.
Rule 1 is what you do before the fight
Rule 2 is what you do to start a fight
Rule 3 is what you do to end a fight
Rules 4 and 5 are considerations for the fight
